The COMSOL Desktop® is the integrated user environment for creating and managing simulations in the COMSOL Multiphysics® software. It includes the Model Builder window, model tree, Graphics window, as well as menus and toolbars with a multitude of modeling tools. In this blog post, we will show you how to customize the user interface and use a variety of keyboard shortcuts to get the most out of the modeling process.

To help understand the complicated universe we live in, we have compartmentalized physics phenomena into distinct disciplinary specializations. However, natural and engineering problems often cross these utilitarian borders. A major strength of the COMSOL Multiphysics® software is the ease with which such cross-disciplinary interactions, which we refer to as multiphysics interactions, can be accounted for. The COMSOL® software provides a plethora of built-in multiphysics couplings and even enables users to implement their own physics couplings.

In a previous blog post, we looked at setting up a programmatic sequence of operations under the Study node for solving, saving a model to file, and exporting data to file. Today, we are building on this knowledge to show how an entire sequence of images can be automatically exported after solving a model in the COMSOL Multiphysics® software.

Little-known functionality of the Study node is its ability to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In this blog post, we take a closer look at this capability. If you use the COMSOL Multiphysics® software, there is a good chance you will find this information useful in your modeling work.

When making improvements to a model in the COMSOL Multiphysics® software, you are likely to add more parameters and variables. As the complexity of your model grows, it can become difficult to keep track of where these parameters are being used and defined, as well as to recall them for use in the settings of other nodes. In this blog post, we show you how to use the Auto Completion and Find tools for efficient model setup.

The COMSOL Multiphysics® software helps you find solutions to your engineering questions, but you may also have questions on using the simulation software itself. Therefore, we’ve created resources to guide your modeling process. In this blog post, we discuss three help tools that you can access in COMSOL Multiphysics: the Help window, Documentation window, and Application Library. We also link to a video that shows you how to access and use these tools at the end of this post.

The Application Libraries, accessed directly in the COMSOL Multiphysics® software, contain an ever-growing number of examples filled with valuable information on how to model certain types of problems, use certain features, and employ specific modeling techniques. To get the most out of the Application Libraries, you should be able to easily find the information you need.

Do you ever find yourself performing the same modeling operations over and over again in each new model file that you work with? Or do you work with colleagues who send you model files that you have to manually add physics and features to? If so, you can greatly accelerate your workflow by using methods, new as of version 5.3 of the COMSOL Multiphysics® software. Let’s find out how.

Sometimes a simulation runs longer than needed, not giving us a way to monitor intermediate results or stop conditionally. This can leave us staring at the monitor, ready to pounce. In this blog post, we discuss how to automate this process in the COMSOL Multiphysics® software. This way, we can work on something else while the software checks the conditions after each step. We also have the option to see what happens the first time the conditions are violated.

The Open Recovery File feature is a somewhat unknown feature in the COMSOL Multiphysics® software, but it’s useful for anyone running simulations that give multiple solutions. If, for any reason, the software shuts down before the simulation finishes, you can open a recovery file so that you don’t lose your work. Here, we highlight a tutorial video on how to open these files to recover “lost” work as well as go over the strengths and limitations of this feature.

Do you find yourself creating new models in the COMSOL Multiphysics® software faster than you can launch them interactively in the COMSOL Desktop® environment? If having to wait for your current model to finish solving before launching the next one does not sound appealing, it’s time to learn how to run your simulations in Batch mode from the command line. As it turns out, this is quite a simple process.
